V.S.O.P.(99/05) Computer Code System
170 S., 2005
V.S.O.P. is a computer code system for the comprehensive numerical simulation of the physics
of thermal reactors. It implies the setup of the reactor and of the fuel element, processing of
cross sections, neutron spectrum evaluation, neutron diffusion calculation in two or three
dimensions, fuel burnup, fuel shuffling, reactor control, thermal hydraulics and fuel cycle costs.
The thermal hydraulics part (steady state and time-dependent) is restricted to HTRs and to two
spatial dimensions. The code can simulate the reactor operation from the initial core towards
the equilibrium core.
V.S.O.P.(99 / 05) represents the further development of V.S.O.P. (99). Compared to its
precursor, the code system has been improved in many details . Major improvements and
extensions have been included concerning the neutron spectrum calculation, the 3-d neutron
diffusion options, and the thermal hydraulic section with respect to `multi-pass'-fuelled pebblebed
cores.
This latest code version was developed and tested under the WINDOWS-XP - operating
system. The storage requirement for the executables and the basic libraries associated with the
code amounts to about 15 MB. Another 5 MB are required - if desired - for storage of the
source code (- 65000 Fortran statements).
